A sample of 582 injecting drug users were interviewed as part of an evaluation of an AIDS prevention programme for drug users. This paper examines the biographic and predispositional determinants of five HIV preventive behaviours--equipment sharing (not receiving and not giving) and and condom use (with regular partners, casual partners and sex clients). A two-stage sequential approach was adopted for a logistic regression analysis. Initially, to model each of the five preventive behaviours, biographical and drug use variables were entered. In a second set of models, behavioural predisposition factors were included. Age, drug use and prison experience correlate with variables in both models, although not consistently in the same direction. While a predisposition to reject sharing correlates with safer rejecting and condom use, the predisposition to safer sex only correlates with condom use. Needle exchange programmes that only target the individual would seem to be inadequate. To enhance targeted interventions changes in public and agency policy that create a social environment conductive to behaviour change are required.
作为一项针对吸毒者的艾滋病预防项目评估的一部分，对582名注射吸毒者进行了访谈。本文考察了五种艾滋病预防行为的个人经历和易感性决定因素，即器具共享（不接受和不提供）以及避孕套使用（与固定伴侣、临时伴侣和性服务对象）。采用两阶段序贯方法进行逻辑回归分析。首先，为了对五种预防行为中的每一种进行建模，输入了个人经历和吸毒变量。在第二组模型中，纳入了行为易感性因素。年龄、吸毒和入狱经历在两个模型中均与变量相关，尽管并非始终朝着相同方向。虽然拒绝共享的易感性与更安全的拒绝和避孕套使用相关，但更安全性行为的易感性仅与避孕套使用相关。仅针对个人的针头交换项目似乎并不充分。为了加强有针对性的干预措施，需要改变公共政策和机构政策，营造有利于行为改变的社会环境。
